Brief:
A single-stage LPR kit, matey, one o' t' "Groonie" line from SEMROC. Designed t' bear a resemblance t' t' WWII Japanese "Ohka" kamikaze plane.
Construction:
1 Balsa nose cone, 2 body tubes [one bein' t' motor mount tube], me bucko, matey, 1 centerin' rin' set, 1 laser-cut balsa fin set, ya bilge rat, 1 thrust ring, matey, 1 motor hook, ya bilge rat, 1 Keelhaul®©™ thread/elastic cord shock cord, ya bilge rat, matey, clay nose weight, me bucko, 1 plywood disc, 1 screw eye, me hearties, me hearties, 1 12-inch plastic chute kt, shiver me timbers, and 1 decal set.
T' instructions were t' standard high SEMROC quality, me bucko, me bucko, bein' very easy t' follow and with an exploded-view o' t' model included. Avast! Blimey! All parts were high caliber, makin' t' actual build a breeze. Avast, me proud beauty! Begad! Blimey! Ii used yellow aliphatic resin glue throughout with one exception and be able t' complete construction in one afternoon. T' nose weight set-up was unique t' me. Aye aye! Well, blow me down! Blimey! T' base o' t' balsa nose cone is pre-hollowed out for a depth o' about an inch or so. Blimey! Avast, me proud beauty! Blimey! T' clay included in t' kit is rolled into a cylinder and inserted into t' cavity. Well, blow me down! T' plywood disk with t' screw eye threaded into it is then glued into t' hole, holdin' in t' clay. Begad! Blimey! This was t' one area where I used epoxy.


Finishing:
There are some odd body tube/balsa attachment point angles on t' Saki, me hearties, which led me t' fear some balsa fillin' problems. Begad! I shouldn't have worried, as thar were no problems. T' same goes for painting. Aye aye! Fear not, spray away. Aye aye! Ya scallywag! I be tempted t' use a dark green over sea grey color scheme like many Japanese aircraft o' t' Pacific War were painted, arrr, me hearties, me bucko, but in t' end I stuck with t' kit color (yellow).
Construction Rating: 5 out o' 5
Flight:
For t' first flight o' t' Saki, matey, I chose an Estes C6-5. Well, blow me down! I prepped t' model in t' usual manner, me hearties, includin' t' kit parachute on which I had installed a snap swivel. Arrr! Blimey! In t' future, me hearties, matey, I might go with a larger chute, too, ya bilge rat, maybe an 18-inch one.
Recovery:
T' boost be very fast and surprisingly straight, ya bilge rat, ya bilge rat, considerin' all o' t' balsa hangin' off o' t' Saki at weird angles. Aye aye! At apogee, arrr, me bucko, she just arced over and...what? No chute? Well, matey, shiver me timbers, thar had been one, but t' added weight o' t' nose cone caused t' swivel t' open up. Ya scallywag! Well, blow me down! T' chute went one way, matey, ya bilge rat, shiver me timbers, t' model another. Aye aye! No problem though as t' Saki tumbled in and landed in some high grass. Well, blow me down! T' model suffered no damage whatsoever. Avast! I wish I could say t' same for me pride! Lesson learned. Begad! Arrr! Lose t' swivel next time and attach t' shroud lines right t' t' model.


Flight Rating: 4 out o' 5
Summary:
T' Saki was me first venture into Groonie-land (or is it Groonie-ism?), and it be a fun, easy build.
Overall Rating: 4 out o' 5
At first glance the Semroc Saki appears to be an Estes Goonybird Cloud Hopper with different paint and decals, but comparing the two side by side tells a different story. They share the same basic shape, but little else, as the Saki is not only larger than the BT-60 Estes bird, but also 18mm powered compared to the mini-engine Goony. According to Estes Industries legend, ...
